Description

 CX-S403G fiber optic switch is an unmanaged intelligent PoE switch, 4 Gigabit PoE ports + 1 Gigabit uplink network port + 1 Gigabit uplink SFP + 1 Gigabit Combo, of which 1-4 ports support IEEE 802.3 af/at standard PoE power supply, single port PoE power up to 30W, and the PoE port can automatically detect and identify powered devices that meet the IEEE 802.3af/at standard and supply power to them through the network cable, non-POE devices intelligently detect no power supply and only transmit data.
It can supply power to PoE terminal equipment such as IP phones, network cameras, wireless APs, video intercoms, and smart homes through network cables. It is suitable for hotels, schools, factory dormitories, and small and medium-sized enterprises to form cost-effective networks.
PoE technology (Power over Ethernet) is Power over Ethernet technology, which refers to providing DC power supply for some IP-based terminals (such as IP phones, wireless access APs, network cameras, etc.) while transmitting data signals. technology, these devices that receive DC power are called powered devices

Features

• 4 Gigabit PoE ports + 1 Gigabit uplink network port + 1 Gigabit uplink SFP + 1 Gigabit Combo
• Comply with IEEE 802.3, IEEE 802.3u, IEEE802.3x, IEEE802.3ab standards
• Ethernet port supports 10/100/1000M adaptive
• Flow control mode: Full duplex adopts IEEE 802.3x standard, half duplex adopts Back pressure standard
• Store-and-forward switching mechanism
• Comply with IEEE 802.3af/at PoE power supply standard
• Three-speed intelligent dial switch (switch function can be customized) :

VLAN: port isolation mode, 1-4 ports realize monitoring network downlink ports are isolated from each other, communicate with uplink ports, effectively suppress broadcast storms, and protect intranet security.
PoE forced power supply: ports 3~4 become forced power supply mode, the power of a single port can reach 30W, and when the power of a single port exceeds 30W, the power supply of the port will be automatically cut off, and the power supply will be automatically restored after the port overload is removed.
AI watchdog: PoE watchdog mode, 1-4 power supply ports support PoE watchdog function, when port communication fails, the corresponding port PoE will automatically restart, reducing on-site maintenance costs.

• The PoE port supports a priority mechanism. When the remaining power is insufficient, the power supply of the high-priority port is given priority to avoid overloading of the device.
• Ports 1~4 support AI recognition of long distances. When the cable length is less than 100 meters, the default rate is 1000M. When the cable length is greater than 100 meters, the corresponding port rate is automatically reduced to 10M. The PoE power supply and data transmission distance can be extended to 250 meters
